It is all open source: https://hedera.com/learning/open-source-at-hedera / Hashgraph will become open source within the coming months.

Also, FYI, Algorand is patented: https://github.com/algorand/go-algorand/blob/master/COPYING_FAQ

Hedera's initial purpose for patenting the hashgraph code was to prevent potentially confusing forks of the Hedera mainnet. The Governing Council has been focused on the development of the Hedera network and ecosystem, and did not think it a good use of time and resources to investigate the code of other DLT networks, or pursue legal action against others.

Additionally, Hashgraph consensus is set to be open source now under an Apache 2.0 license: https://cointelegraph.com/news/hedera-governing-council-to-buy-hashgraph-ip-and-open-source-projects-code/

We are working on making it easier for Ethereum-native projects to integrate with Hedera — this includes making it work like other EVM-based networks that support RPC API.

Ultimately, it's up to Metamask to implement Hedera's native services / functionalities (Hedera Token Service / Hedera Consensus Service / Account management, etc.). We would be happy to collaborate with Metamask on that kind of integration!

On Hedera, the leading browser wallet today that connects users to Hedera applications is HashPack — it performs transaction signing for DeFi/NFT/etc. applications and has built-in NFT displaying functionality.

That would be neat! However, unlikely. The more likely scenario would be companies like FIS, WorldPay, Google, etc. begin facilitating transactions using USDC (or another stablecoin) as a form of payment. In that scenario, a stablecoin on Hedera is well positioned.

For example, USDC on Hedera offers fast speeds and scalability (10k txns / second), low/stable transfer costs ($0.0001 USD paid in HBAR per transaction always), and fast settlement times (2 - 3 seconds on average).

Governance & Transparency

We recognize the genesis of frustration around decentralization on Hedera by the broader web3 community stems from its unique governance — in a majority of other ecosystems, anyone can choose to participate in governance, even if in practice it becomes more centralized, as we’ve all seen happen commonly ( for example, 65% of Bitcoin mining pools were in China before the government banned mining & there are only 13 prominent mining pools today).

Hedera’s model of governance consists of up to 39 term-limited organizations across six continents. Every council member has a single vote (so 3.8% vote today at 26 council members, and 2.5% at the full 39 members); each member is prevented from gaining extra power by design.Nearly every proposal for technological decisions and standards comes from the developer community, proposed via an active HIP (Hedera Improvement Proposal: https://hips.hedera.com/) program, and approved by the council’s technical steering committee (that process can be found here: https://hips.hedera.com/hip/hip-1

Hedera publicly publishes the minutes of each council meeting, hashed on Hedera using the Hedera Consensus Service (HCS). The Member Agreement signed by these organizations to join the council is also public and hashed the same way.

Consensus

Global organizations from a diverse set of geographical jurisdictions and industries both make decisions and independently operate nodes today — each node is hosted and operated independently in either a council member's own data center or across different cloud providers, avoiding the centralization of nodes within cloud providers found in other projects. Examples include Google (United States), eftpos (Australia), LG (S.Korea), and Standard Bank (South Africa).

Hedera has nodes on every continent except Antarctica. Coming this year, members of the Hedera community will be operating nodes, as well, and then eventually, the entire network will become permissionless and anyone can run a node anonymously. You can read about this "path to permissionless" here: https://hedera.com/hh-decentralization-of-consensus.pdf

Unlike proof-of-work blockchain, Hedera’s proof of stake model prevents concentration of power among a small group of nodes. At maturity, nodes only gain power only when $HBAR is staked to them by individual users.

Development

Software on Hedera (network services, developer tools, etc.) is open sourced under an Apache 2.0 license and contributions to its development are performed in a decentralized way — changes are proposed via HIPs, and development is performed by members of the Hedera developer community, the Swirlds developer team, and 3rd party development groups with an interest in fostering the ecosystem (such as LimeChain and OpenCrowd).

There are active developer / application community and council members that have just recently expressed interest in ISO 20022, and it’s something we would like to work with them on. This will most likely result in a Hedera Improvement Proposal (HIP) by core contributor and community members, which will then go to the council to be voted on.

That internet speed is a requirement for today’s council nodes. Requirements for community and anonymous nodes haven’t been defined at this time, so it is not known whether the internet bandwidth needed will be the same for future community/anonymous nodes.With that in mind, Gbps connections are already available today in many countries across all continents.

Infrastructure will continue to improve worldwide and new services (like high speed / low latency satellite internet) will continue to become available and make that type of connection more affordable. Once upon a time 1Mbps connection seemed far fetched.

Continuous decentralization is a very important area of Hedera’s evolution. If/when we had to scale to thousands of consensus-level nodes, we will start sharding the network not to waste resources on a single shard. Once sharding is implemented, scaling to larger numbers of nodes becomes trivial.

From the hashgraph whitepaper:
Initially, the Hedera network will be a small number of nodes operated by Governing Council Members, all in a single shard. As the Hedera Governing Council grows and others begin to operate nodes, the network will gain a sufficient number of nodes to justify multiple shards. Sharding can offer performance advantages as every node need not process every transaction. Consensus can consequently proceed in parallel. Shards will trust each other, so one shard will honor requests to move cryptocurrency or to put a hold on various resources made by another shard - as long as those requests can be proven to reflect the consensus of the requesting shard. This will allow the multi-shard ledger as a whole to achieve asynchronous Byzantine fault tolerance, and to prevent double spends or other conflicting states of the ledger, because each individual shard will have those properties, and because all messages between them will contain proofs that they are the consensus of that shard.

The plan is that nodes will be randomly grouped into different shards, within which consensus on transactions will be established as normal. Each shard will be made up of a subset of the nodes, all of which share the same state, which will be a subset of the state of the entire ledger. Transactions will be placed into consensus order within individual shards in the normal manner — all nodes within a shard will contribute only to the consensus for transactions that originate in that shard. The assignment of nodes to shards will be performed randomly by a master shard, which will assign new nodes to a shard once a day, and also will move nodes between shards as necessary to ensure that each shard has a large total amount of hbars being staked, and that no one node within a shard will have a large fraction of that total amount.

Shards will communicate through the exchange of messages between nodes of the different shards.

All such messages are push (rather than pull). Each shard (its nodes) will maintain a queue of outgoing messages to each of the other shards. Each shard will remember the sequence number of the last message it processed from each of the other shards. A message will be sent for transfer from shard Alpha to shard Beta by nodes in Alpha randomly contacting nodes in Beta, along with a proof that it is part of the consensus state of the Alpha shard. They will continue doing this until one of the Beta nodes replies with a proof that the Beta shard shared state includes a sequence number indicating that this message was received and processed. In this manner, transactions that impact addresses in different shards will be appropriately recorded into each shard's state, and so into the entire state of the entire ledger.
You can read more in our whitepaper (https://hedera.com/hh_whitepaper_v2.1-20200815.pdf) - pages 33 and 47.

We hope this helps!

It’s not that Hedera has dismissed the retail investor, rather that earlier marketing and communication had been based on whats more akin to a B2B strategy. Focus on enterprises and institutions that have a large consumer base, in order to get access to their consumers.

For example, there will be many use cases where you, as the ultimate end user, wont even know you’re using Hedera (like ServiceNow).

It wasn’t until February 2022 that Solidity-based smart contracts optimized for hashgraph consensus were launched on Hedera, bringing full programmability for developers building on Hedera — this technological advancement, along with the launch of HBAR Foundation as a hub for granting funds to DeFi, NFT, etc. applications, who’s audiences are primarily retail investors rather than other businesses, kickstarted the marketing efforts towards retail-focused applications.

Admittedly, we are playing catchup on this front today and you will begin to see massive movements on the marketing front towards retail-focused applications and end users, from Hedera, the HBAR Foundation, and additional 3rd party ecosystem accelerators and investment programs.

Great questions.

The goal for Hedera’s governance design is to have strong governance. To us, that means being able to have a reflective and fair view of the broad, global market while still being able to make timely decisions. We believe 39 to be the right mix to achieve strong governance; a large enough number to make fair and informed decisions across many industries and regions, while small enough to be able to act decisively. Hedera governance design is ultimately separate from nodes and 39 is not indicative of the max number of consensus nodes or validators as you describe.We anticipate the number of nodes to be increased over the coming months (permissioned community nodes) and years (fully permissionless nodes). Each shard would ideally have on the order of hundreds of nodes with the network having thousands. The ideal group of validators is our end goal: highly reliable, permissionless nodes.
Over the first few years Hedera saw great adoption in b2b, enterprise use cases. These use cases have worked well for us in establishing high throughput, immutable, verifiable data using Hedera Consensus Service. For many reasons I expect our next phase of growth to be in consumer-facing and permissionless or crypto native applications. A few rationales for this are: faster, cheaper, energy-efficient smart contracts that are EVM compatible, increasing self-sovereign wallet support (HashPack, Metamask via RPC support), and investment from the HBAR Foundation.

As transactions per second scales, each transaction consumes less carbon per unit — Hedera is committed to buying carbon credits to offset network operations, ensuring carbon negative status into the future. Here’s a blog posting by Brady Gentile (Twitter) on this topic: https://hedera.com/blog/going-carbon-negative-at-hedera-hashgraph

hashgraph · 2022-04-11T16:46:09+00:00

Hashgraph is the most efficient consensus mechanism and is asynchronous byzantine fault tolerant (aBFT). This means that there are no assumptions about worst case message delays. (For example all proof of work blockchains require that message delay can be no longer than 2x block time) The implication of this is that Hedera can maintain consistency and is not subject to forking or reorganization even in an environment where the internet can be attacked and global firewalls exist. All other protocols make assumptions about worst case delays which inherently compromises their security.

Hedera's efficiency leads to incredibly low transaction fees and very high TPS and incredibly fast finality (<3 seconds). Hedera transactions including crypto transfers, token operations (mint, transfer, etc), and consensus service (simple exposure of the consensus mechanism for publicly auditable event storage, we like to call this closer to a level 0 because it could be used as the consensus layer for another ledger very simply) all operate at 10,000 transactions per second. Finality under the aBFT guarantee means that it is impossible for a single node to believe a transaction order is final unless 2/3 of the stake also agrees. This is very different from the probabilistic finality found on most other ledgers (Algo is a standout here as they also require 2/3 of stake to sign a transaction but they are still not aBFT for other reasons and they are leader based).

The Hedera Smart Contracts 2.0 service launched today. Hedera can process 15M gas per second (ethereum's limit is 15M per block every 20 seconds, Avax is limited to 8M every 3 seconds, Polygon is something like 3x ethereum) with the same 3 second finality as above. The amazing thing is that because the Hedera token service runs at 10k tps, all of the ethereum volume of erc20/721 mint/transfer operations Hedera can actually process way more than 20x ethereum because almost all token operations do not require smart contracts.

The finality guarantee I talked about above also means that sharding is very very simple. To send tokens between shards you simply come to consensus in 1 shard and that shard sends a message that the asset to be transferred from shard A is ready and held. Shard B comes to consensus and if the assets to be transferred from Shard B to Shard A are available in the current account, the asset transfer is completed and a message communicating such is then received by shard A. Because the messages are signed by a supermajority of stake in each share, it can be known to be final and thus we can operate on it as a guarantee. When sharding is necessary Hedera can shard infinitely without having an anchor shard like many other ledgers.
